Key Benefits and Why It Matters

With a 3‑pole design, this breaker protects three-phase circuits, making it ideal for motor loads, heavy equipment feeds, and distribution panels that rely on balanced protection across all phases. The bolt‑on mounting provides a secure, vibration‑resistant connection, which is especially valuable in environments with frequent equipment start-ups or high ambient temperatures.

Practical Use Cases

• Retrofit or upgrade an aging panel with a compatible Siemens protection device to restore reliable fault isolation.
• Replace a failed breaker in a Siemens-ecosystem panel where standardization simplifies maintenance and spare-part management.
• Protect three-phase motors and feeders up to 80 A in manufacturing floors, HVAC systems, or processing lines.
• Implement in new installations where a robust bolt-on solution is preferred for durable bus connections.

Compatibility and Installation Considerations

Before ordering, confirm the fit and ratings match your panel’s specifications. The part number E23B080 serves as the most reliable reference for compatibility with Siemens panels and assemblies. Ensure your enclosure supports bolt‑on mounting and that the bus connection geometry aligns with the breaker’s design. Follow standard electrical safety practices—power down the system, verify labeling, and use appropriate tools to secure the bolt-on connection.

Why Choose Siemens E23B080?

• Part of Siemens’ trusted protection lineup, offering consistent performance across compatible panels and bus assemblies.
